Specification of Letters Patent.

Patented May 1922 Application filed January 6, 1921. Serial No. 435,452.

T 0 all whom it may concern:

Be it known that I, .HENRY E. MYnns, a citizen of the United States,residing at Bowman, in the county of Bowman" and State of North Dakota,have invented certain new and useful Improvements-in Eye Testers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in eye testers andhas for its primary object the provision of means for movably supportinga plurality of eyeglasses containing different lenses between a chartand sight openings, so that a person may be quickly and easily fittedwith eyeglasses containing the proper lenses.

Another object of this invention is the provision of an eye tester ofthe above stated character which will be simple, durable and eflicient,and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which a Fig. 1is a front elevation, illustrating an eye tester constructed inaccordance with my invention,

Fig. 2 is a side elevation illustrating the same and showing the devicein an adjusted position,

Fig. 3 is a longitudinal sectional view illustrating the supportingmeans for the eyeglasses,

Fig. 4: is a transverse sectional view illustrating the same and takenon line 4-4 of F i 3.

fieferring in detail to the drawing, the numeral 1 indicates a casing,the front wall of which is provided with spaced sight openings 2adjacent its upper end and which receives the inner ends of eye shields8. The upper portion of the front wall 2 is slightly concaved so as topermit a person to obtain a position in close proximity with the eyeshield 3.

The rear wall 4; is hinged to the side wall 0 at lower corners. as shown.at ,6 andssai d rear wall is adapted to formqachart-support by having aplurality oftongues 7 struck out therefrom and which areadapted toibebent' over the edgesof a card 8 bearing suitable characters. The card8 is arranged on the rear wall 4 so that the same can be readily readthrough the sight openings 2. i

In operation, the rear wall 4 is moved slightly rearwardly from thecasing 1 so as to permit sufficient light to strike the chart and renderthe same readily readable by way of the eye shield 3.

Segmental shaped plates 9 are pivoted to the side Walls 5 at their rearupper corners and are connected by a top wall 10. The segmental plates 9have formed upon their curved edges right angle extending tongues 11provided with slots 12 to receive the ear engaging pieces 13 ofspectacles or eyeglass frames 14. The ear engaging pieces also engagecurved retaining members 15 secured to the plates 9. The curved edges ofthe plates 9 are arranged in close proximity to the front wall 1 so thatthe various spectacle or eyeglass frames will be supported in rear andin close proximity to the sight openings. The plates 9 are con nected bysuitable handles16 so that said plates may be adjusted for bringing thevarious eye-glass or spectacle frames in alinement with the sightopenings. The spectacle or eye-glass frames are adapted to containvarious kinds of lenses so that on adjusting the plates 9 the properlenses may be brought in rear of the sight openings and the personlooking through the sight openings at the chart may readily determinethe proper lenses.

A flange 17 is formed on the forward edge of the top wall 10 andprojects slightly beyond the front wall so that the same may be readilygripped for raising the top wall and swinging the plates 9 on theirpivots when not desiring to employ the handle.

A suitable partition 18 is located in the lower portion of the casing 1to form an auxiliary compartment 19 in which various articles such asdifferent kinds of lenses and eyeglass frames may be stored.

Any desired type of illuminating means may be placed within the casingfor the purpose of placing the proper illumination on the chart.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination, and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.

What is claimed is: 7

An eye tester comprising a support including side, front and bottomwalls, said front Wall having sight openings adjacent its upper end anda depression between said openings to receive the nose of a person, atop wall pivoted to the side Walls, a rear wall pivoted to the sideWalls adjacent their lower edge and carrying a chart, flanges formed onthe rear walls and adapted to have frictional contact with the sidewalls to hold said rear walls in adjusted positions, segmental shapedplates secured to the top wall and movable Within the side walls, andmeans supporting eye glasses on the curved edges of said plates.

In testimony whereof I affix my signature in presence of two witnesses.

ROGER 1. LEE, N. BODIEN.
